JOHN STEPHENSON, OF NEHV YORK, N. Y.

AXLE-BOX FUR CABLE-CAR TRUCKS.

SPECIFICATION forming part of Letters Patent No. 396,839, dated January 29, 1889.

Application filed February 23, 1888. $erial No. 265,075. (No model.)

To all whom, it III/(1.7] concern:

Be it known that I, .ToHN STEPHENSON, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Cable-Car-dh-lick Axle-Bar Side Arms, of which following is a specification.

Cars adapted to cable propulsion are as yet in an experimental state. One of the unsolved. problems is to construct an easy-riding grip-ear which will carry the grip steadily, always at an equal distancebelow the train-rails. This requires that the grip shall not be suspended or supported on any part of the car structure resting on springs. Various efforts have been made to provide a support of the character required, but as yet without satis factory results.

My invention is intended to obviate the difficulties hitherto unsolved, and for this purpose I prepare a car-axle box I'ittin the usual journal at the end of the axle and having integral with the shell a sidewiseprojecting arm, adapted at the outer end to receive and hold the corner of a truck-carriage or other support adapted to carry the cable-grip and its ad 'juncts as wheel-brakes, track-brakes, guards, and other appliances.

One form in which my invention may be embodied is illustrated in the accompanying drawings, in whieh- Figure 1 is a perspective view of a car-axle box provided with an arm constituting the support of the grip-supporting truck. or carriage. Fig. 2 is a plan of the parts shown in 1. Fig. 3 is an elevation of the parts shown in Fig. 1.

The car-axle box A, constructed in any usual or suitable manner, is supported, as usual, upon the journal a of the axleli. In-

tegral with the shell of the box and constitut-ing an extension of the rear or side wall of the same is the arm 0, which constitutes the bearing for the attachment oi the corner of the truck or carriage which supports the cable-grip and its adjuncts.

As shown, the arm 0 is curved forward near its point of junction with the axle-box, so as to project it outward to support the said truck or carriage outward of the wheels, and is curved downward to support said truck or carriage at some distance below the bottom frame of the car. It is frequently the case that the back of the axlebox contacts with the face of the wheel, and the pedestal also approximates closely to the wheel; therefore the arm permits it to extend between the wheel-face and the pedestal. The straight portion of the said arm is in the form of an angle-plate with its vertical back and horizontal top of such length and strength as to be capable of receiving and holding the end of the truck side rail, although it is possible to dispense with either of the said members of the angle-plate, the other beingmade sutfi ciently strong to constitute the desired support in a direction parallel with-the wheel.

\Vithout limiting myself to the precise construction and arrangement of parts shown, I.

claim 1. A canaxle-box shell with an integral arm from the back vertical corner of the shell extending sidcwise below the top of the shell, substantially as described.

2. A car-axle-box shell with an integral arm extending sidewise in a plane below the box top, the end of the arm having a vertical plane and adapted to hold the corner of the cablegrip frame or carriage, substantially as described.

A car-axle-box shell with an integral arm extending sidewise and terminating in anglebar form, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN STEPHENSON.
